ASTM F2170
Standard Test Method
for Determining Relative
Humidity in Concrete Floor
Slabs using in situ Probes.

1
Introduction
The osiTector CMM IS concrete moisture meter measures the
relative humidity and temperature in concrete slabs using in situ
probes, prior to the application of flooring materials or coatings.
When applying flooring materials or coatings to concrete, it is
critical to ensure that the moisture level inside the concrete has
decreased to acceptable levels. If not, moisture can accumulate
below the flooring or coating, causing discoloration, cupping,
buckling, blistering, adhesive failure and mold growth.
Designed in accordance with ASTM F2170, the osiTector CMM
IS provides a complete measurement solution for monitoring the
drying process of concrete slabs in compliance with industry
standards. The unique design of the osiTector CMM IS probes
allow the user to place them into concrete immediately after the
holes are drilled and leave them in place until they reach
equilibrium, eliminating the need to reopen the hole at a later
date.
osiTector CMM IS probes broadcast measurements to the
osiTector App (pg. 9) or osiTector Advanced instruments
(pg. 11) using Bluetooth wireless technology.
The osiTector CMM IS is available in 3 kit configurations:
Basic, Co plete and Professional.

Viewing Readings from osiTector CMM IS probes
osiTector CMM IS measurement values can be viewed using
the osiTector App or a osiTector Advanced instrument. To
record measurement values, see How to Measure (pg. 7)
Using the osiTector App:
Install the osiTector App from the App Store (Apple iOS) or
Google play (Android).
Open the osiTector App. Available probes within 10 m (30 feet)
will appear as “CMMIS” with the corresponding serial number, as
shown below:
The small circle icons to the left of each osiTector CMM IS
probe display the most recent Relative Humidity reading. This
value is updated every five minutes.
To view measurements from the
osiTector CMM IS probe, select it from
the search screen. Once connected, a
blue light is emitted from the bottom of the
probe and values are updated every five
seconds and displayed as shown to the
right. The battery indicator in the top left
corner shows the battery level of the
osiTector CMM IS probe.

Using a osiTector Advanced:
To view available probes, select Bluetooth Smart from the gage’s
Connect menu. Then select Smart robes (shown below):
Available probes within 10 m (30 feet) will appear as “CMMIS”
with the corresponding serial number and latest relative humidity
reading, as shown below:
Select a probe to display its Relative Humidity and Temperature
values. Once connected, a blue light is emitted from the bottom
of the probe and values are updated every five seconds.
When a osiTector DPM environmental probe is
attached to the osiTector body, osiTector CMM IS
measurement data can be recorded into the gage’s memory.
When any other probe is attached, such as a osiTector 6000
probe, osiTector CMM IS readings can be viewed only.
NOTE:
Calibration
Calibration is typically performed by the manufacturer or a
qualified lab. All osiTector CMM IS probes include a Certificate
of Calibration. In accordance with ASTM F2170, probes must be
recalibrated annually. DeFelsko recommends beginning the
calibration interval from either the date of calibration, date of
purchase, or date of receipt.
Verification of Accuracy
It is recommended that osiTector CMM IS probes be stored

within the Calibration Check Chamber when not in use. The
Calibration Check Chamber and Saturated Salt Solution are
designed in accordance with ASTM E104 to maintain a constant
relative humidity. Per ASTM F2170, the Calibration Check
Chamber and Saturated Salt Solution maintain a constant relative
humidity of 75% (at 25° C) and keeps the probe in a ready-to-use
condition.
ASTM F2170 requires calibration to be verified within 30 days
prior to use. Power-up the probe by inserting a battery, positive
(+) side up. Probe calibration is verified by inserting a probe into
the Calibration Check Chamber, connecting to either the
osiTector App or a osiTector Advanced gage body and
taking a measurement (after allowing the probe at least 1 hour to
acclimate to the present environment). Probes should report a
relative humidity within 2% of the humidity value listed in Table 1
for the corresponding temperature. To simplify the verification
process, we recommend using the Cal Check function of the
osiTector App or osiTector Advanced. The Cal Check
function automatically determines whether a probe is reading
within tolerance.
Probes should be allowed to acclimate for at least 24 hours within
the Calibration Check Chamber and Soluble Salt Solution before
calibration is checked.
It is important to maintain a constant temperature within the
Calibration Check Chamber. Relative humidity variation due to
temperature fluctuation for the Calibration Check Chamber is
shown in Table 1.
Table 1
Extracted from Table A1.1,
Equilibrium Relative Humidity Values
for Selected Saturated Aqueous Salt
Solutions (ASTM E104)
Exa ple Tolerance Calculation:
At 25° C, the Soluble Salt Solution relative humidity range is
75.3% ± 0.2. Including the ±2% relative humidity tolerance
specified in ASTM F2170, a probe would be considered to be in
tolerance if it measured between 73.1 – 77.5 %.
When the Saturated Salt Solution (Boveda) is completely
dry, it will solidify. They should be replaced while there is still
moisture present and before they are completely solid.

osiTector CMM IS probes, coupled with the osiTector App or
osiTector DPM Advanced simplify the process of viewing,
recording and reporting in accordance with ASTM F2170.
Step 1. Evaluate the location to determine how many tests must
be performed.
ASTM F2170 specifies that 3 tests must be performed
for the first 100 m2 (1000 ft2) of concrete and one
additional test for each 100 m2 (1000 ft2) of concrete.
One test must be performed within 3 ft. (1 m) of each
exterior wall.
Step 1b (if using the PosiTector App). The osiTector App
makes it easy to view, record and report in accordance with ASTM
F2170. The app is available within the App Store (Apple iOS) and
Google play (Android).
Open the osiTector App and select F2170 from the top
menu bar. Next, select New roject and enter the job
details.
A osiTector DPM Advanced instrument or spare
osiTector CMM IS probe can be used to record ambient
temperature as required by ASTM F2170. Under Ambient
Instrument, select an available osiTector DPM Advanced
or osiTector CMM IS probe. To enable broadcasting,
ensure the osiTector Advanced is powered on (Bluetooth
Smart enabled) or the battery in the osiTector CMM IS
probe is installed.
How to Measure (in accordance with ASTM F2170)
Select Ok to save the project.

Step 1c (PosiTector App only). If desired, insert a picture or
blueprint of the area to be measured. Use the to take a
photo of the blueprint, or use the to insert an image from
the photo gallery. This background image will make it easy to
locate each probe within the area.
Step 1d (PosiTector App only). Press the (+) icon at the bottom
right of the Project screen and then touch the screen in the
desired location to place the hole. The new hole location will be
overlayed on the image and will be identified as a circle containing
--- 0. Repeat this for each measurement location within the Area.
Create additional Areas as required.
Step 2 – Drill the Hole
ASTM F2170 sets out strict requirements for hole depth and
diameter. Using a rotary hammer drill with a carbide-tipped
masonry drill bit (¾” diameter), drill the hole to the required depth.
Do not use water for cooling or lubrication.
Hole depth requirements according to ASTM F2170:
nConcrete slab drying from one side only:
40% depth from top of slab
nConcrete slab drying from two sides:
20% depth from the top of the slab

8
Step 3 – Clean and Inspect the Hole
Ensure any dust and debris are removed from the hole. The
vacuum attachment included with the Complete Kit and ro Kit
is ideal for this purpose. It can also be purchased separately from
your dealer.
Per ASTM F2170, check the diameter and depth of the hole using
the included tape measure. If either dimension is incorrect, the
hole must be re-drilled and cleaned. Incorrect hole diameter may
cause difficulty inserting or removing a osiTector CMM IS
probe.
If using the PosiTector App, touch the circle corresponding to the
a hole, and record the location, depth and date/time the hole was
drilled. Select Set Now to input the current time and date, or input
it manually.
Step 4 – Insert the robe
osiTector CMM IS probes are designed to be placed into the
hole as soon as the hole has been prepared. Remove the probe
from the Calibration Check Chamber and Saturated Salt Solution,
unscrew the battery cover and insert the battery, (+) positive side
up. Replace the cover.
The probe will immediately begin broadcasting readings via
Bluetooth, and can be viewed from the osiTector App (pg. 9)
or a osiTector Advanced (pg. 11).

9
Once powered-up and operational, insert and push the probe
completely to the bottom of the hole. Cover the hole using the
included yellow plastic cap. Per ASTM F2170, the probe must
remain in the hole for 72 hours to achieve moisture equilibrium
before measurements are recorded.
If using the PosiTector App, touch the circle corresponding to the
hole, and select the serial number of the inserted probe to
associate that probe with the hole.
Record the date and time each probe is inserted by selecting Set
Now to automatically set the current time and date, or input it
manually.
A new battery will continuously power the probe for up to
3 weeks.
NOTE:
Step 5 – Record Measurements
ASTM F2170 requires waiting 72 hours, before probe
measurements are recorded. There is no need to remove the
yellow cap or to access the probes in the holes. The probes
remain powered-on and broadcasting while in situ.
To Record Measurements Using the osiTector App:
1. Open the osiTector App and select F2170 from the top
menu bar.
2. Open the associated Project.

10
3. Record measurements for each hole in the project:
To record probe measurements, touch the circle
corresponding to the hole and touch the Measure button to
record the Relative Humidity and Temperature within the
corresponding hole.
Ambient Relative Humidity and Air Temperature (above the hole)
can be recorded using a spare osiTector CMM IS probe or
osiTector DPM Advanced instrument. The ambient instrument
being used is specified within the roject setup (pg. 6). Select
Measure, and then Ok to store the displayed values. Alternately,
a relative humidity and temperature value can be entered
manually.
Repeat Step 3 for each hole in the project. Once readings have
been recorded for all holes in the project, professional reports can
be generated that conform to ASTM F2170. Select RE ORT from
within the Project to automatically generate the report.
More detailed instructions on using the osiTector App is
available in the Help File, located at www.defelsko.com/app-help
NOTE:

11
To Record Measurements Using a osiTector DPM Advanced:
1. Access the Connect Menu within the gage menu.
2. Under Bluetooth Smart, select Smart robes (shown
below). Available osiTector CMM IS probes will be visible.
Select the probe to be recorded.
3. The relative humidity and temperature measured by the
osiTector CMM IS probe will be displayed below the ambient
relative humidity, air temperature and surface temperature
measured by the osiTector DPM probe, as shown below:
To record, ensure a batch is open in memory and press the (+)
button on the gage. The displayed readings of the osiTector DPM
probe and the osiTector CMM IS probe will be recorded into the
gage’s memory. If a batch is not currently open, select New Batch
from the gage’s Memory menu. To add measurements to an
existing batch, select Open from the gage’s Memory menu.
Measurements from multiple osiTector CMM IS probes can be
recorded within the same batch by repeating the above steps for
each probe in the project.

12
If any probe other than the osiTector DPM probe is
attached to the osiTector Advanced body while connected to
a osiTector CMM IS probe, the gage body will ignore the
attached probe and only display the osiTector CMM IS
measurements.
Recorded measurement values can be reported using PosiSoft
Solutions. See the osiTector DPM Instruction Manual for more
information.
Step 6 – Remove the osiTector CMM IS robes
The osiTector CMM IS probes are designed to be reusable.
Once measurements are complete, use the extraction tool to
remove the probes from the holes. Clean any visible debris or
concrete dust from the probes and inspect the silicone fins. If the
silicone fins are damaged or worn, they should be replaced. If no
further tests are required, remove the batteries by unscrewing the
battery covers and pushing the battery out using the probe
extraction tool and place each probe into a Calibration Check
Chambers for storage.
Once testing is complete, the holes should be filled with a
cementitious patching compound in accordance with ASTM
F2170.
NOTE:
Specifications Range Accuracy Resolution

Troubleshooting
The osiTector CMM IS robe does not appear in the
osiTector App or in the osiTector Advanced Gage Body
after the battery is inserted
Check the battery in the probe and replace if required. Ensure
Bluetooth is enabled on the Smart device running the osiTector
App or Bluetooth Smart within the osiTector body.
RH value is slow to stabilize
If the probe is exposed to very low humidity for an extended time
period and then placed in a high humidity environment, the
displayed Relative Humidity (RH) may appear to respond slowly.
Allow the probe to stabilize at least 60 minutes for a change of
RH greater than 50%. When placed into the Calibration Check
Chamber, allow at least 24 hours for the relative humidity to
stabilize.
Returning for Service
For issues related to the osiTector CMM IS probes:
1. Install new batteries in the proper alignment as shown within
battery compartment.
2. Examine the sensor for debris or damage.
3. Re-attempt measurement.

CMM IS

1
Introducción
El medidor de humedad de concreto PosiTector CMM IS mide
la humedad relativa y la temperatura en las losas de concreto
utilizando sondas in situ antes de la aplicación de piso o
revestimiento del suelo.
Al aplicar materiales de piso o revestimiento del suelo, es
fundamental asegurarse de que el nivel de humedad en el
concreto haya descendido hasta niveles aceptables. Si no, la
humedad podría acumularse bajo el piso o revestimiento
provocando decoloración, abarquillado, pliegues, ampollas, fallos
en la adhesión y crecimiento de moho.
Diseñado según la AST F2170, el PosiTector CMM IS ofrece
una solución completa de medición para el control del proceso
de secado de losas de concreto en cumplimiento de las normas
de la industria. El diseño exclusivo de las sondas del PosiTector
CMM IS permite al usuario colocarlas en el concreto
inmediatamente después de haber realizado las perforaciones y
dejarlas en ellas hasta que se alcance el equilibrio, eliminando
la necesidad de abrir de nuevo el orificio posteriormente.
Las sondas PosiTector CMM IS transmitirán las mediciones a la
App PosiTector (pág. 9) o a los instrumentos PosiTector
Advanced (pág. 11) utilizando la tecnología inalámbrica
Bluetooth.
El PosiTector CMM IS está disponible en 3 configuraciones:
